1. Insufficient memory
2. Network and telecommunication conditions
The memory is a processing space for running the game, not for storing.
Therefore, spare space in memory is necessary.
If the game collides with other apps while playing it, it may cause a problem.
Therefore, please make sure that unused apps are uninstalled and check on other applications
running unnecessarily on the background.
Unstable network conditions are one of the main reasons why games crash,
so we recommend playing on a stable network.
We are putting in our best effort to assure the best environment for you to play our game
and we will keep up to provide the best service.
Thank you.
